To aZZ whom it may concern:

Be it known that I, JAMES HANSON HUSSEY,

'of Spokane, in the county of Spokane and State of Washington, haveinvented a new and useful Improvement in Mechanical Movements, of whichthe following is a specification.

My invention is in the nature of an improvement in mechanical movements,my object being to reduce to aminimum the motive power necessary tomaintain a constant motion.

My invention consists in the novel construction and arrangement of partsherein described and claimed, and illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of mechanismillustrating the principles of my invention. Fig. 2 is a rear elevationof similar mechanism with the walking-beams shown in section. Fig. 3 isatop plan view of the walking-beam employed with my invention. Fig. 4 isa perspective view of the balancing-car.

The invention,broadly speaking, comprises mechanism interposed betweenthe driving power and the work it operates upon whereby the powerderived from a reciprocating motor is evenly delivered to the work.Taking for purposes of illustration the commonest form of motor now inuse, the steam-engine, it is a well-known fact that the power derivedtherefrom is delivered with constant-variation, according to theposition of the crank-shaft of the engine, position of the piston, 66c.

Referring to the drawings, A A indicate suitable towers upon which thewalkingbeams and operating-levers of my device are supported. Thesetowers are two or more in number, and the two sides of each towerparallel with the main shaft are strongly braced with angle-irons. ThesebracesA are socured to the corner-posts of the towers by rivets.Suitably supported at the top of each tower upon the short bars A is theshaft a, upon which the walking-beam B is balanced. The main drive-shaftO, carrying the flywheels D, is supported upon a suitable foundation E,said shaft C being disposed beneath the walking-beams and in a line atright angles to them. Each walking-beam is reinforced by the truss-rodsB B on each side thereof. These rods are secured to the beam at each endby the bolts B walking-beam is provided with the cones B which operateas spreaders to hold the rods suitably separated from the beam at theircenters. Each of these rods is provided with a turnbuckle B forimparting the necessary tension thereto from time to time.

The wrist-pin B is carried by each walkingbeam at a suitable distancefrom its center and projects outwardly at one side of said beam to beengaged by the upper end of the connecting-rodF, the lower end of saidrod engaging the crank D of the fly-wheel D on the main shaft. It willbe noticed that one of these cranks is set ninety degrees in advance ofthe other, so that while one of the cranks is passing over itsdead-center the other will always be in position to exert the greatestpower upon the load. If three Wheels with driving-cranks are used, thecranks are then set at an angle of one hundred and twenty degrees toeach other, so that the force exerted upon the main shaft to revolve thesame will remain practically constant whatever the position of thedifierent cranks with reference to their deadcenters maybe.

The walking-beam is preferably operated from its end opposite thatcarrying the wristpins B I In order to adapt a long beam, as I haveshown, to be operated by an engine of comparatively short stroke, Iemploy the construction illustrated in Fig, 1, in which A is a bracketforming a support for the bellcrank lever G, said support being securelyriveted to the tower A and having pivotal connection for the bell-cranklever at G. The said lever has the short downwardly-extending arm G andthe longer arm G3 at right angles to the arm two arms areunited by thebrace-section G The pitman or piston-rod H of the engine has pivotalconnection with the lower end of the short arm G2 of the bell-cranklever, while the longer arm G3 of said lever carries at its outer endthe connecting-rod I, which forms the connection between the bell-cranklever and the walking-beam.

When my invention is used in the propulsion of ships, I provide themeans illustrated in Fig. 1 for steadying the walking-beam when the shipis rocked in a rough sea. Said Atits center the G The outer ends ofthesemeans consists of the transverse guide-bar B, rigidly secured to the endof the walkingbeam adjacent the fly-wheels and having bifurcated endscarrying the friction-rollers B adapted to travel in the channels Bwhich are suitably disposed with reference to the walking-beam and areof a curvature corresponding to the arc of a circle described by the endof said beam when in operation. These channels are parallel to eachother and are rigidly secured to the ship, so that they only move as itmoves. On the top side of the half of the walking-beam adjacent theengine is the counterbalance-weight, preferably in the form of a car J,adapted to be moved longitudinally on said beam to produce anequilibrium of lever-power between the engine and the work, thusinsuring a more steadyand even movement of the machinery. When the loadis such that the weight of the car itself is not suflicient to producethis effect, weights may be placed within it. For lighter machinery,where the variation of load is not so great, a solid block of ironadjnstable on the beam in the same way that the car is adjusted willordinarily be sufficient 'for every requirement. The carJmoves uponflanged rails J, secured, preferably, by bolts J to the walking-beam.The flanges of these rails extend inwardly from their tops and engage acooperating flanged section J carried by the bottom of the car.Intermediate the section J and the car J is the spacing or separatingsection J which elevates the top section of the car sufiiciently abovethe rails to prevent it from contacting with the bolts J". The flangedsection J of the car may, if preferred, simply consist of a transversebar socured to the section J at each end of the car, as indicated indotted lines in Fig. 4. The section J of the car isprovided with a threaded aperture designed to receive the threaded shaft J having at itsouter end the operating hand-wheel J. This shaft is mounted in suitablebearings at each end, so that the car maybe moved in or out by revolvingthe handwheel.

The main shaft of the mechanism herein shown (see Fig. 2) is providedwith a crank K preferably midway between the fly-wheels, and to thiscrank is connected the machinery to be operated upon by my device,provided said machine is of the nature of a pump requiring areciprocating movement to be imparted thereto. The said main shaft Oisalso provided with the band-wheel L for forming the connection betweenmy device and such machinery as is to be operated by belts.

It should be borne in mind that myso-called walking-beam is of thenature of a lever, its center representing the fulcrum, the work doneand the machinery operated by the wristpin the weight, and the end withthe car the point where power is applied.

Usually the wrist-pin is removed from the center of the levera distanceequal to the radius of the fly-wheel, while the length of the lever isusually equal to about twice the diameter of the fly-wheel.

When very long levers are required, they may be made in sectionssuitably secured together by bolts. I prefer that each section shallconsist of a single piece of wroughtsteel the full length and width ofthe lever and that a sufficient number of these shall be bolted togetherto give the required thickness and strength. For small sizes the leversmay be made of solid cast-steel.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
